Background:  Widespread and growing sources of electromagnetic radiation raised concerns attributed to the potential adverse health risk of radiofrequency fields. Given the functional importance of the hippocampus, this study aimed to investigate the effects of electromagnetic waves radiated by mobile jammer on hippocampal expression of p21 and p53 genes as regulators of cellular apoptosis...

Nowadays jamming causes the major data loss in mobile communications. During the transmission time Anti-jamming technique can be used to transmit intermittently at low power in order to conserve energy. Here we use 802.11wireless network technology and this is to access the functions of the physical layer. There are two functions called Rate Adaptation and Power Control are used to find out whe...

144 Abstract— Every year, innumerable road accidents and deaths take place due to distracted driving. Large number of studies shows mobile phone usage while driving was the major reason for distracted driving. With the aim of preventing road accidents due to mobile phone usage while driving, we propose a highly efficient automatic electronic system for early detection of incoming or outgoing ca...

With the rapid evolution of computing paradigms and the increasing popular of mobile devices, newly emerging mobile computing paradigms become more and more prevalent, such as crowd-souring computing, human-centred computing, mobile cloud computing etc. Moreover, with the emergence of new computing paradigms, communication networks experience unprecedented transformation which greatly improves ...

introduction : the fast-growing telecommunication and wireless technologies has led to more dependence to these communication devices and higher levels of exposure to electromagnetic radiations propagated by cellular devices and their service towers. to disable signaling in places where silence is valued or where information quarantine measures are required, mobile phone jammers emit radiofrequ...

Background: Substantial evidence indicates that exposure to electromagneticfields (EMF) above certain levels can affect human health through triggering somebiological responses. According to WHO, short-term exposure to EMF at the levelspresent in the home/environment do not cause any apparent detrimental effects inhealthy individuals. However, now, there is a debate on whether long-term exposur...

We investigate the behavior of two users and one jammer in an AWGN channel with and without fading when they participate in a non-cooperative zero-sum game, with the channel’s input/output mutual information as the objective function. We assume that the jammer can eavesdrop the channel and can use the information obtained to perform correlated jamming. Under various assumptions on the channel c...

A Wireless Sensor Network (WSN) is a self-configure network of sensor nodes communicate among themselves using radio signals and deployed in quantity to sense, monitor and to understand the physical world. A jammer is an entity which interferes with the physical transmission and reception of wireless communications. Reactive jamming attack is a major security problem in the wireless sensor netw...

The theory of stochastic vector quantisers (SVQ) has been extended to allow the quantiser to develop invariances, so that only"large"degrees of freedom in the input vector are represented in the code. This has been applied to the problem of encoding data vectors which are a superposition of a"large"jammer and a"small"signal, so that only the jammer is represented in the code. This allows the ja...
